云冈石窟景区晴天太阳辐射模型研究

Clear-sky Solar Radiation Model Study on the Yungang Grottoes Scenic Spot

基于Haurwitz辐射经验公式,我们建立了云冈石窟景区太阳辐射热计算模型,该模型可计算出任意一天在晴空条件下,时间间隔为5 min的全天辐射热瞬时数值。同时,利用该模型计算所得的辐射数据集结合当地气象站实测数据资料,我们比较了晴天和阴天的温度及辐射热差异。该模型不仅可以补充和完善当地气象数据,而且可以为云冈石窟的维护和修缮提供前期所需要的精确太阳热辐射气象资料。

Based on the Haurwitz empirical radiation formula, we established the solar radiation calculation model for Yungang grottoes scenic area. The model can calculate the solar radiation instantaneous value throughout the day under the condition of clear sky, which time interval is 5 minutes. At the same time, the temperature and radiant heat differences have been compared on a clear and cloudy day, which using the data set of the model computed and the measured data of the local weather stations. The model can not only supplement and complete the local meteorological data, but also provide the accurate solar thermal radiation meteorological data for the repairing and reinforcing of the Yungang grottoes at its early stage.
